Wyo928

Newbie here, slowly going over the 928 I bought a few weeks ago. Learning a lot here, thank you! Got most of my electrical sorted out for now with lots of wire brushing, new ground wire, fuses, tighter belt...

On to the auto tranny. Found great pics and advice on newer Bowden cable adjustments. No luck, so far, finding pics and advice for the '82. But that's okay, I can see mine. I've got mine apart and can see only three cables. One from the pedal, one to the tranny, one- I assume- for cruise control? I see how to adjust the cable to the pedal. The other cable goes back to where I can look up on top of the tranny and see the other end. I think that if I drive over my hands they will then be flat enough to fit up in that space nicely, where, I assume, the adjustment needs to take place. Is that right? Is the adjustment really up there where it looks to be? Any tricks for getting to it without dropping the tranny?

If I can even snug up both those cables (they have tons of slack) will that be the right thing to do?

Any suggestions?

Later... a couple of pics. I assume the adjuster is under the rubber boot above the tranny in one pic.

Other pic shows the three cables, two already unhooked at the ball. The one that's easy to see is the one to the pedal, the lower one goes back to tranny, the middle one- cruise control?

Bowden cable is adjusted at the tranny.

It took me several tries of going up and down on the lift to finally get the right tension.

When it's right you'll know it.

Adjustments are made in the engine bay - adjust cable to throttle first. Then Bowden, then gas pedal, then cruise (loose). Sorry, I'm on my phone, so if no one else chimes in, I'll give more info when I get home later.

I could be wrong - are the older ones different than 87+ ?

On my 84, I adjusted the cable by loosing the locknut at the socket connection at the intake and turning it either in or out to make it shorter or longer..... However in your picture it looks like you are out of threads to make it any shorter.....
Im not sure if you can use this same proceedure back at the tranny connection

All I know is 82.

But I can't see why Porsche would reverse the adjustment process and stick it on the the throttle assembly. ??

Shark,
Yep, the adjustment is on the Right side of transmission at the lever arm.

Wyo,
Why do you want to 'snug up' the control pressure control valve cable ('Bowden Cable') ? I'm very familiar with S4 adjusting of cables, etc... but they are not to be done just to 'snug up'. Adjustments are made relative throttle control cable state. Someone will chime in who is familiar with your MY (model year).

MainePorsche

On the S4's and up the adjustment of the 'Bowden Cable' is made at the cable quad under the hood.

Maleficio

Well, I guess that makes sense in the end.

It's certainly easier to pop the hood than to lift the car.

Landshark87

Good lord, adjusting it at the TRANSMISSION?!? Took me about 5 tries to dial it in. Yikes.

Maleficio

It took me at least four tries on the lift.

MainePorsche

Whatever cable that is, he's certainly out of threads there for shortening.

Okay, so, I want to adjust cables because, from what I've read, that's the response to a sluggish AT. They show a lot of slack.

I pulled the top ball and adjusted it 1/4" just to see if I could and haven't put it back. I gather, from responses, that the adjustment for bottom cable is under that boot above the tranny. Fun.

The third cable is, I gather, cruise control.

Apparently, for '82- or, at least, mine, there's only three cables and can't adjust them all conveniently.

Should I not be looking to take out the slack?

Thanks! It's a big help to be able to talk this out.

Wyo,
On the S4, here is the order of cable adjustments. First, is the throttle cable - it is adjusted so that as soon as there is tension on it you should hear the click of the throttle position sensor. When you have this done you next adjust the 'Bowden Cable'. Initially set it up with slight slack. The final adjustment for this is done by driving it, and adjusting to perfect timing of the shifts. Once you have set the initial 'Bowden Cable' tension, then set the cruise cable with slack and then set the pedal cable to a reasonable position. Drive it then find the right Bowden setting for your 'perfect' shift timing. On the S4 I took a 7 & 8 mm wrench and was able to adjust while on the road. Unfortunately it looks like you will have to get under it after each run. It is important that the throttle cable be set appropriately first. This is for the S4. Probably similar to your MY. Wait to see if someone chimes and confirms this for your MY.
Best Wishes
